After a sojourn in Italy, the Fields return home to celebrate Hester's 45th birthday. Despite William's back going out, and some complications arising from misunderstandings, they settle on dinner out to celebrate whereupon Hester is summoned to deal with an emergency at Lucy's Kitchen. This turns out to be a ruse as the restaurant is packed with their friends for a surprise party, and Guy and Nancy announce that they were re-married that morning, leaving Hester in floods of happy tears.
